Videos, games, photos, GPS functionality and more. The iPhone can do a heck of a lot, especially considering the fact that it's a phone and not a PC. One thing it's not quite adept at is integrating a lot of that into the actual "phone" part. Enter MetaSwitch and their clever little app, Thrutu.

Thrutu makes true on-the-phone multitasking possible. Users can take and share photos, contact information, their current location and more with a tap or two. The mileage one gets out of this largely depends on how they tend to interact with people over the phone, but certain aspects of its usefulness are pretty obvious. Sharing location info makes random, and even planned, meet-ups much simpler than "I'm standing over by the big duck." Getting a friend's opinion remotely on a new outfit can be done instantly. It even cuts down the time needed for those "Let me get you the number" situations.

It's important to note that Thrutu does require some initial setup. Users have to register their phone number in order to use the service, and it can only work when both ends of the conversation have the app installed. Fortunately, it's also set up to sort through contact lists for Thrutu users (with default contact lists still available), and there's a handy Invite button for anyone without it.

Keep in mind that, because Thrutu is designed to send various amounts of digital information, it also requires a 3G or wi-fi connection. There are bound to be some areas where it's largely ineffective (like when on a camping trip or on the subway) and some contacts who just won't be able to make proper use of it. Then again, if these people have a smart phone chances are they have access to at least one of the two.

Thrutu certainly shows enormous potential, both as a personal use app and one for more business-oriented users. There are a few small hoops to jump through in order to get it going, but once everything is set up it's smooth sailing. The real trick is to get everyone using it. I guess that means I've just done my part.
